Application filed February 15, 1908. Serial No. 416,132.

To all 'whom it may concern:

Be it known that I, ISAAC R. CnEcELiUs, a citizen of the United States, residing in the county of Gibson and State of Indiana, have invented certain new and useful Improvements in Coupling Devices, of which the following is a specication.

his invention relates to cou ling devices, and more particularly to coupllin er plower driven vehicles and ot draft vehic es.

It has for its object to provide such a coup- Afacilitate short turns and which will direct the rearmost'vehicle to any portion of the roadway.

Another object is to provide such an article of a simple structure, which may be manufactured largely from stock material.

Other objects and advantages will be apparent from the following description and it be understood that changes in the specific structure shown and described may be made within the scope of the claims without de arting from the spirit of the invention.

n, the drawings forming a ortion of this specification and in which l' e letters and numerals of reference indicate similar parts in the several views: Figure 1 is a side view of a traction engine equi ped with this structure and drawing a roa scraper, Fig.'2 is a detail sectional view of the shift gear, Fig. 3 is a sectional view on line 3-3 of Fig. 2 and Fig. 4 is a detail ofthe sliding coupling mem- Referring now to the drawings, there is shown a traction engine of the usual type having a platform 11 to which the shifting mechanism A is secured in a suitable manner.

.The shifting mechanism A compiises a yrack bar 13 supported by portion 14 carried by the platform 11 and having secured upon its upper and lower faces L-beams 15 having oppositely projecting vertical anges'l to serve as guides for the sliding couphng member 17. The sliding coupling member 17 comprises a yoke stamped from heavy sheet arms inwardly directed to form flanges 18 en- 16. Registering openings 19 are formed in the upper andlower a shaft 20 is revolubly openings '19, and carrying at its upper end a hand'wheel 21. A gear Wheel 22 is secured to the'gshaft between the arms of the yoke 17 and is engaged with the rack bar 13 to move gs betweenv of exceedingly said yoke having s y lub the coupling member laterally when rotated. Spaced ears 23 are stamped from the bight of the yoke and have engaged therebetween the forward end of a tongue 24 carried by the veliicle drawn. Perforations 25 are formed in the ears 23, and engaged downwardly therethrough and also through an eye 25 in the end of the tongue24 there is a coupling pin 26, as shown.`

I t will be seen from the brief description that a shifting gear is provided which will be simple structure and that it will be effective in operation. The vehicle attached 'thereto may be guided over any part of the road, the extent of its operation eing limited only by the length of the rack bar 13 and attached guides.

Tie rods 30 are secured of the yoke to hold the arms in spaced relation.

What is claimed is:

l. In a geared shiftable coupling, a yoke member adapted for slidable engagement with a rack member and carrying operative means for shifting the yoke longitudinally of the rack member, 'said yoke being stamped from sheet material, and having spaced arms, the outer ends of which are bent inwardly for engagement with a guide portion,

aced rearwardly extending ears stamped t ierefrom and adapted for coupling engagement with a vehiige.

2.` In a laterally shiftable ceiipling, the combination with a rack bar having op ositely extending flanges, of a cke memliei stamped from sheet metal, said yoke membezVA having spaced arms, the outer ends of which are bent inwardly and engaged over the flanges carried by the rack bar, said yoke having spaced rearwardly extending bars stamped therefrom, and 'adapted for coupliner engagement with avehic e, agear revocairied between the spaced arms, and mes ed with the rack bar, and means for rotating said gear to move the yoke longitudinally of the rack bar. metal and having the ends of its opposite 3. A geared shiftable coupling, comprising a yoke member stamped from sheet material and comprising opposite arms having their extremities turned inwardly, said yoke having spaced horizontal perforated ears stamped from its bight ortion for coupling engagement with a vehicle to be drawn, a rack bar having op osite flanges engaged slidably inwardly of t e inwardl f turned portions of the yoke, the gear carried revolubly to the outer ends betweenfthe arms of the yoke in mesh With .therafck bar, and means for .rotatin the gear to shftthe lcoupling longitudinal y of the' .'raek bar. l l,

4. In a shifta'ble coupling, a coupling memberadapted to be engaged Withl a rack bar, and ada ted'to carry means for sliding the coupling ongitu'd'mallyof 'the rack bar, said coupling comprising a yoke stamped 10 from sheet material'and having spaced: arms the outer ends of which are bent'mwardly to form engaging flanges', said yoke having alsospaced perforated ears stamped from' its b1ght portions and adapted for coupling engagement with a vehicle to be drawn.
